基于运行速度的山区公路改扩建设计选线研究
|
摘要
为解决山区改扩建过程中路线设计不能有效结合实际情况而导致造价过高的问题,对山区改扩建公路根据路段特征进行划分,分为平纵指标较好路段、纵坡较大路段、临河路段、过城镇路段等,针对不同路段提出具体的路线设计方案,并结合安全性评价方法对路线设计方案进行评价分析,将评价分析的结论反馈到路线设计方案中,对路线进行调整或提出相应的安全措施,保证路线设计的合理性,使路线不仅符合现场实际,降低工程造价,更能符合改扩建项目的远期规划。
In order to solve high cost problem caused by ignorance of actual situation during the route design of reconstruction and expansion in mountainous areas,this paper firstly divides highway of the reconstruction and expansion in mountainous areas into sections with better horizontal and vertical indexes,sections with larger longitudinal slopes,sections near rivers and sections passing through cities and towns,according to the characteristics of sections,and puts forward some suggestions for different sections.According to safety evaluation method,conclusion of the evaluation and analysis feeds back to the route design plan,the route is adjusted or corresponding safety measures are put forward to ensure the rationality of the route design,after that not only the route conforms to the site reality,but also the cost is reduced,which is more in line with the long-term planning of reconstruction and expansion projects.
